MARKER ATTACHMENT FOR PLANTERS.

SPECIFICATION formingpart of Letters Patent No. 633,446, dated September 19, 1899.

Application filed June 2 8, l 8 9 9- To all whom it may concern:

Beitknown that I, JOHN GILMOUR, of Troy Grove, in the county of La Salle and State of Illinois, have invented a new and Improved Marker Attachment for Planters, of which the following is a full,clear,and exact description.

My invention relates particularly to a means for changing the gage or marker for cornplanters; and the object of the invention is to provide a simple system of levers which will enable the driver withoutleaving his seat to raise the runner of the marker out of the ground and throw the gage or marker to the right or left, as required, and simultaneously raise the shovels or cultivator-wheels.

Another object of the invention is to provide a means whereby the gage or marker may be heldin an upright position and readily dropped to the side.

Another object of the invention is to avoid the use of the check or guide rope usually employed to manipulate the gage or marker, and thus obviate the necessity of the driver passing the reins over said rope at each change of gage.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawing, forming a part of this specification, which is a perspective view of the improved attachment, the marker or gage being shown in two positions.

The frame A is adapted for attachment to the rear of the planter in any approved manner, and said frame is supported by wheels 11, and the said wheels are mounted to turn upon an axle 12, properly secured to the frame. The frame A likewise supports a drivers seat 1%, the main standard ll of said seat being bifurcated.

A main lever 15 is fulcrunied between its ends at the bottom portion of the seat-standard 14:, and the rearwardly-projecting section 15 of this main lever 15 is adapted to be operated by the foot of the driver when such operation is most convenient; otherwise the main lever 15 is operated by hand through the medium of an attached handle 17 which is within convenient reach of the drivers seat Serial No. 722.192. (N0 modelfl and is provided with a suitable thumb-latch 18, adapted for engagement with a rack 19, secured to the seat-standard 14:. The forward end of the main lever 15 is connected by a chain 16 or its equivalent with the plow-beams or other supports for the cultivator blades or shares. (Not shown.) served that the lever 15 when manipulated will either raise or lower the plow-beams, and this action may be accomplished in the ordinary manner; but the main lever 15 is further utilized to operate the gage or marker B simultaneou sly with the operation of the plowbeams, and this dual operation is accomplished in a manner that will shortly be eX- plained.

A secondary or auxiliary lever 20 is pivoted between its ends near the upper portion of the seat-standard 14:, and a connecting-bar 21 extends from the rear portion of the main lever 15 to the forward portion of the upper v or auxiliary lever 20, and the rear end of the upper or auxiliary lever 20 is provided with an attached chain 22, cable, or its equivalent, and said chain or cable 22 is secured to an eye or its equivalent attached to the draw-bar 23 near the inner end thereof. This draw-bar 23 is adapted to enter stirrups or notches 13, located at the rear side portions of the main frame A, the draw-bar entering said stirrups when the gage or marker is in operation.

The gage or markerB is provided with the ordinary runner 24 at its outer end, and the draw-bar 23 is attached to the gage or marker at a point preferably between its center and its inner end. The draw-bar 23 is at an acute angle to a line drawn longitudinally through the frame A, and the inner end of the drawbar 23 is pivoted upon a rock-shaft 25,which rock-shaft is mounted to turn in a rear bar 26 of the frame A and in a socket 27, secured to the axle 12 of said frame or to any near-by support. The rear end of the rock-shaft is provided with a head 28, and the inner end of the gage or marker is pivoted in said head. In operation when the gage or marker is to be shifted from one side to the other the foot portion 15 of the main lever 15 is pressed downward or the handle 17 is drawn toward the driver, whereupon the gage or marker will be carried from the horizontal position Thus it will be obat the right-hand side of the m achinefor eX- ample, to the perpendicular position shown in dotted lines and over the center in direction of the left-hand side of the m achine-and the said gage or marker, by manipulating the said main lever 15, may be permitted to drop quickly or slowly to the reverse side of the machine to that at which it was formerly placed. If, however, it is desired to hold the marker in a substantially vertical position, this may be accomplished by causing the thumb-latch 18 of the hand-lever 1'7 to enter a suitable notch in the rack 19 when the marker has been carried to one side of a perpendicular line. Thus it will be observed that when the hand-lever 17 is released from the rack the gage or marker will drop to the desired side portion of the machine, the stirrups 13 serving to hold the marker in working position through the medium of the drawbar 23. It is also obvious that the marker or gage is operated simultaneously with the operation of the plows or shovels.

Having thus described my invention, I

pivoted between its ends on said seat-standard above said main lever, a link connecting said main lever and the forward end of said auxiliary lever, and a connection between the rear end of said latter lever and the draw-bar, as and for the purpose set forth.

JOHN GILMOUR.
